I’d argue that the hardest part of learning legal citation is not
mastering The Bluebook, not learning the italics and the abbreviations
and the periods. Rather, it’s learning the judgment required to know what to cite, and when, and for what purpose.
After all, as a system of communication that is built upon precedent,
legal writing in the Anglo-American legal system depends on citation in
ways that other fields do not and never will. Citation is integral to how our meaning gets made.

Amen to that. Sure, you need to figure out the rules for citing law review articles, treatises, cases, and the rest. But that's just a matter of looking up the rules and following examples. The harder task if figuring out when to cite a law review article, a treatise, or a case.
